Apparently I still know more than you about what it means, because the sentence is directly related to her own work product.
That means Susan Rice doesn't need permission to access her own product. And it also means that if she leaks information that McMaster gave her access to, it will be information that she already knew about since it's her work product to begin with.
Quit trying so hard. You're all sweaty.
Yes it's about her former work product but it's also about any other classified information that she has had previous access to.
Eliminating the Need to Know for Rice, gives Rice the power to determine if and when she wishes to see those classified items. She will not need to demonstrate a need to know to anybody up the security chain.
If McMaster wants to leave her clearance in place, it would be better to leave in the Need to Know requirement, that is required by almost everybody else with a security clearance.

LOL, it's like hitting watermelons with a baseball bat.
